CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 350,399, dated Oletober 5, 1886.

Application filed June 4, 1886. Serial No. 204,157. (No model.)

u Fig. 3 is a perspective view of the latch. Fig.

4 is a similar view of the modified form of latch, and Fig.- 5 is aperspective view of the f link common to both forms of latch.

The invention consists in the construction and arrangement of parts, as will be hereinafter fully described and claimed.

A A represent portions of cars to which the draw-heads B B are secured in any suitable manner. The draw-heads have the usual fiaring mouths, and are formed with recesses B', opening upward in rear of the mouths. The bottoms of the recesses B B have recessed shoulders b b, as shown in Fig. l, and the side walls of therecesses, at their rear ends, have open bearings b,leading from the upper edges of said side walls. The draw-heads are further provided with rabbeted covers or top plates,

c C C,to close the top of recesses B B,and bearing b b', lthe forward ends of the covers being apertured at c c for the coupling-pins. Within `the recesses B B are placed the U-shaped latches D D, whichY have cross-pieces D at their outer ends, their inner ends being extended outward to form pivots D2, which rest in the bearing b and are held from displacement by the covers C C. Coupling-pins E extend down through the Openings c c in the covers and through apertures in the crosspieces D of the latches, shoulders being formed in the said pins abovethe cross-pieces. In the left-hand coupling the pin E is secured to the crosspiece D, or formed integral with the latch, so that when raised the latch willbe raised also 5 but in the modified form the pin passes loosely through the aperture in the cross-piece, so that it may be operated without Operating the latch, the latter being-pro'- vided with side arms, D2, connected with its pivots D2 D2, and extending forward and upward therefrom, and connected by a crosspiece,D*,l1aving an apertured lug,D5. Levers F are pivoted to the ends of the cars and have operating-handles at their ends. A short chain, G, conncctsthe pin E of the lefthand coupling with the pin F,while iu the modified form the chain F connects the lever with the latch through the medium of the apertured lug D5, so that in each instance by operating the lever the latch and pin will both be raised, while in the modified form the pin E may be separately operated without raising the latch.

H represents the link, which is slotted loetween its end cross-pieces, H, to receive the ends of the couplingpins which pass therethrough into sockets in the draw-heads, as shown in Fig. l. From the crosspieces H project the inclined projections H2 H2, which are separated by slots,to allow the lower ends of the coupling-pins to pass through anddrop behind the cross pieces of the links, the cross-pieces D'of the latches falling behind the shoulders H3 formed by the rear vertical faces ofthe projections H2. The forward ends of the projections H2 terlninatein lugs H",which engage the recessed shoulders b in the drawheads,to prevent the links from being thrown upward by the sudden j arri ng ofthe cars.

The parts kas will be seen may be readily replaced in case repair is necessary, and nosprings are required,and the strain on the couplingpins is relieved by the latches D.

Having thus described our invention, wha we claim as new, and desire tosecure by Letters Patent, is

l. The combination,with the draw-head B, having a recess, B, of the latch D, provided with pivots D2 at its rear end,a cross piece,D,

piece D, pivots D2, passing through the bearings b', arms D3, extending forward and upward from the pivots D2 at the outside of the draw-head, and connected by the apertured cross-piece D, and the pin E, extending down through the said aperture, substantially as set forth.

3. The combination, with the draw-head 5 having the recess B, and the shouldered recess b in the bottom thereof, and the coupling pin,of the lilik H,having cross-pieces H', having inclined projections at its opposite ends terminating in the lugs H", adapted to engage Io said shouldered recess, substantially as set forth.

4. The combination, With the draw-head B, having the recess B open at its top, the open bearings b, leading from the upper edges ot' the side Walls of the said recess, the latch D, having pivots in said bearings, and the coupling-pin, of the cover C, closing` the recess B, and bearings b, and provided with aperture c for the coupling-pin, substantially as set forth. 5. The combination, with the draw-head B, having recess B', having:r bearings bin its side Walls and shouldered recess b in its bottom, of

the latch D within the recess B', and provided with pivots Dl and cross-piece D', the coupling-pin E,extending above and below the said cross-piece, the link H, having end crosspieees H, inclined projections H2, forming vertical shoulders H and terminating in the lugs H, and means for operating the latch and pin, substantially as and for the purpose set forth.

6. The link I-I, formed With the end crosspieces 1-1, the inclined projections l-Il at its opposite ends, forming shoulders H, and terminating in the lugs H H, substantially as set forth.

fitness our hands and seals this 7th day of April, lSSG.
